Unemployment Insurance and Unemployment Spells
检验失业保险的金额和期限对失业持续时间的影响，发现高福利会降低离职概率，但福利到期前离职概率会急剧上升，对政策制定者和劳动经济学家有参考价值。
This paper tests the effects of the level and length of unemployment insurance (UI> benefits on unemployment durations.The paper particularly studies individual behavior during the weeks just prior to when benefits lapse.Higher UI benefits are found to have a strong negative effect on the probability of leaving unemployment.However, the probability of leaving unemployment rises dramatically just prior to when benefits lapse When the length of benefits is extended, the probability of a spell ending is also very high in the week benefits were previously expected to lapse.Individual data are used with accurate information on spell durations, and the level and length of benefits.Semipararnetric estimation techniques are used and compared to alternative approaches.The semiparametric approach yields more plausible estimates and provides useful diagnostics.
